Can someone explain, why you think Florida is in Hillary's pocket??
2012: D 42.9%, R 39.1%, Other 18.1%, total Dems +170k
2016: D 39.6%, R 39.1%, Other 18.9%, total Dems +32k
(today is not included)
I took date from http://www.electproject.org/
Why is so good? Yes, I know many Dixies switched to Reps. Other is more Clinton-friendly. But how does this data implies that Florida is gone for Trump? Probably slightly lean D, but gone?
No entiendo nada 
Robby Mook did say he believes Clinton is ahead by about 170k in FL. This point in 2012, he said the Obama campaign thought they were down 15k. I don't believe it's in the bag for Clinton but it's definitely looking good.
